1 Construction Sikagard Protective and Decorative Coatings and Sealers for Exterior Concrete and Masonry CMYK

2 The Sika Range of Coatings Sika s Protective Coatings offer a first and lasting line of defence against concrete s natural enemies: carbonation, chlorides and water. Corrosion of the steel embedded in concrete represents the greatest risk to any concrete structure. Two major causes of this corrosion are carbonation and chloride ion intrusion. Sika Canada Inc. Presents its Range of Protective and Decorative Coatings for Exterior Concrete and Masonry Featuring Sikagard 550W Elastocolor and Sikagard 670W coatings designed not only to enhance the appearance of concrete structures, but more importantly, to protect them against deterioration and damage. These two systems are designed specifically to protect concrete buildings and structures against: Carbon dioxide and water ingress - the root causes of carbonation, reinforcement corrosion and concrete deterioration. Chloride ion ingress from atmospheric and environmental sources which diminishes the protection provided by concrete to reinforcing steel, leading to corrosion-based concrete damage and potential loss of structural integrity. Atmospheric gases, acid rain and other air-borne pollutants which also contribute to concrete contamination. CARBONATION: Initially, concrete, a highly alkaline material, provides the perfect protection against corrosion. Over time, however, inadequate design, contaminated constituents, poor placing of reinforcement and concrete, exposure to environmental influences and the impact of concrete defects make it possible for atmospheric carbon dioxide to react with the calcium hydroxide in concrete and form calcium carbonate. This phenomenon, called carbonation, results in the reduction of the ph value of the concrete, thus neutralizing the natural protection provided by the concrete to the reinforcing steel. Once this occurs, corrosion is made possible when moisture and oxygen reach and react with the embedded steel. Sikagard 550W Elastocolor and Sikagard 670W now available in over 450 factory-produced colours! For the first time, all the protective benefits of the Sikagard range of water-based coatings -- perfectly matched to your colour requirements -- thanks to the new Sika ColorWorks program! Sika is proud to introduce its colour-matching program, one of the best in the industry. Simply select your desired colour* by referencing the Sika ColorWorks colour fan, indicate the ColorWorks Code when specifying or ordering, and your coating will be produced, in factory, to the desired colour. It s that simple! And best of all, no minimum quantities are required. *In addition to the ColorWorks Program, Sikagard Protective Coatings can also be produced to custom-matched colours. CO 2 Carbonation Front

3 Carbonation Front Chlorides: H 2 O+CI Threshold CI - Profile Sikagard Chloride-induced corrosion occurs when the concrete is exposed directly or indirectly to chlorides via de-icing salts, contaminated construction materials, or in marine environments. When the chloride ions reach the reinforcement, they destroy the passivating film on the steel, even in uncarbonated concrete, making it vulnerable to corrosion when moisture and oxygen are present. By using the ColorWorks ColorWorks Sika Coatings Years of use around the world have shown Sika coatings to offer: Sikagard protective coatings, an additional long-term barrier is created between the reinforcing steel in the structure and the naturally-occurring elements. Durability: long-lasting coatings which increase the service life and reduce maintenance of the structures to which they are applied Protective properties offering protection against the ingress of moisture and aggressive gasses and chemicals Environmentally-friendly, water-based, VOCfree formulations created to support LEED Certification requirements Excellent weather and freeze/thaw damage resistance Water-vapour permeability, thus allowing structures to breathe Resistance to dirt pick-up and mildew Long-lasting UV resistance and colour stability Highly aesthetic, smooth or textured finishes Low maintenance finishes which can easily be refreshed Sika s coatings are designed to prevent the ingress of aggressors such as moisture, chlorides, carbon dioxide, and the gasses and pollution which compromise the ph level of the concrete surrounding the steel rebar. They are water vapour permeable -- to allow your structure to breathe -- and resistant to the UV light which causes so many coatings to fail.

4 Sikagard Coatings Rigid vs. Flexible vs. Elastic Coatings: How to Choose? Protective coatings for reinforced concrete, whether rigid, flexible or elastic, are all designed to protect buildings and structures to varying degrees from the elements which eventually lead to deterioration and Sikagard 550W Elastocolor Sikagard 670W Sikagard Color A50 the corrosion of reinforcing steel. This corrosion or rust in turn, An elastic coating designed to beautify and offer long- An environmentally-friendly, flexible coating, designed to A flexible coating, also designed to protect and beautify buildings can cause expansion within the concrete and ultimately, staining, cracking and spalling of the concrete from the rebar, leaving it lasting, maximum protection on buildings and structures subject to micro-cracking. Buildings prone to micro- protect and beautify structures not subject to dynamic cracking. Flexible coatings are ideal for structures where dynamic not subject to dynamic cracking. As with the Sikagard 670W, it is designed for use on buildings and structures not exposed to the environment and to further corrosion. cracking require an elastic shell, capable of accommodating and bridging existing and future cracking is not an issue. Like Sikagard 550W Elastocolor, Sikagard 670W protects against prone to dynamic cracking. Unlike Sikagard 670W, it has a solvented formulation which Rigid coatings offer static dynamic micro-cracks. Rigid or flexible coatings, however the ingress of moisture, gasses and chemicals, the sources of makes it possible to apply it and have it cure at temperatures as protection and serve primarily to enhance the aesthetic value of a structure; because they are inflexible, they cannot respond good, don t perform adequately on these types of structures; cracks develop, the coating is breached and opportunities for the ingress of moisture and reinforcing steel corrosion, thus increasing the durability of any structure to which it is applied. Designed for use on above-grade, low as 0 C (32 F). It, too, is breathable, protects against the ingress of water, carbon dioxide and chlorides and provides excellent weathering properties. appropriately to dynamic and crack-inducing movement in structures without eventually being breached. other contaminants are created.

Two coats of this self-priming coating are all you need to protect and aesthetically enhance concrete, brick, and block. removed. Unlike the first two types of coverings, elastic coatings deform under stress from external forces and then return to their original shape when the stress is removed. This makes them ideal for structures subject to dynamic, crack-inducing movement.

5 Sikagard Sealers For Sheer Protection of Concrete and Masonry Structures: Sika offers a range of unpigmented, hydrophobic sealers which do not alter the decorative integrity of concrete, Sikagard SN100 Sikagard SN40 Sikagard SX10 masonry and brickwork on buildings and structures. In Sikagard SN100 is a penetrating monomeric silane solution which forms a water-repelling layer within the surface of concrete and masonry. It penetrates deep into substrates where it resists abrasion, creating a long-lasting barrier against water and weathering. It acts to reduce corrosion by significantly restricting water and waterborne chloride ion intrusion, while allowing the concrete and masonry to breathe. Because it contains 100% active ingredients, it is a high performance product suitable for both horizontal and vertical surfaces. Approved by the Alberta Ministry of Transportation as a Type 1c sealer, it is designed for use on traffic-bearing surfaces under demanding conditions, such as on parking garages, bridge decks and ramps, or similarly exposed structures. Its VOC content is less than 300g/l. While Sikagard SN40 offers essentially the same features as the Sikagard SN100, it is a more economical version for use in less demanding environments. It contains 40% active ingredient and is approved by the Alberta Ministry of Transportation as a Type 1a and 1b sealer for use on bridge decks, abutments, parkades and barrier walls. It is also approved by the Ministère du Transport du Québec under standard MTQ Sikagard SX10 is composed primarily of a siloxane solution, which reacts in contact with atmospheric moisture and forms a polysiloxane layer, a transparent water-repellant. It is an effective, economical treatment for use on vertical surfaces, such as solid or hollow-core brick and block walls, exposed aggregate concrete panels and concrete façades and retaining walls. Treated surfaces shed many water-borne pollutants and are easier to clean, thus protecting the original appearance and integrity of the structure. general, sealers consist of hydrophobic (water-repellent) impregnations which are capable of resisting various degrees of moisture ingress, from driving rain to water under pump action as a result of passing vehicles. Sealers are typically used on buildings and structures to reduce the passage of water and chloride into the building fabric......which, in turn, minimizes the availability of moisture as a catalyst for reinforcement corrosion. Additionally, protection against the ingress of water reduces the harmful effect of damp upon people, materials and equipment, protects against pollution-based staining and damage due to repeated freeze/ thaw cycles. Sealers are not resistant to carbon dioxide diffusion and thus carbonation, are incapable of bridging dynamic cracks, and do not offer the same life expectancy as coatings.

6 Primer/Base Coats Optional, Complementary Primer/ Base Coats for Use with the Sikagard 550W Elastocolor and Sikagard 670W Systems Though the Sikagard 550W Elastocolor and 670W coatings are typically primerless, Sika has created two complementary products to enhance their performance for use under particular situations: Sikagard 552W Aqua Primer for use on chalky or excessively porous substrates Sikagard Elastic Base Coat to provide textured or smooth, high build undercoats. Where required, the use of Sikagard 552W Aqua Primer on excessively porous or chalky substrates can facilitate application, reduce consumption and optimise the adhesion of the protective coatings. The use of Sikagard Elastic Base Coat is designed to increase the aesthetic value of the Sikagard coatings: the textured formula, in particular, is recommended to hide surface blemishes and imperfections, and to diminish the appearance of surface undulations. The smooth formula offers an economic alternative to a first coat of the Sikagard 550W Elastocolor. Both bridge dynamically moving cracks, protect against the ingress of carbon dioxide and chlorides and are water vapour permeable. Both products are suitable for use with Sikagard 550W Elastocolor and Sikagard 670W, and can be used conjointly.

This effect is experienced with all silanes as a class, whether waterborne, solvent borne or 100% silanes. As partially reacted compounds at the time of manufacture, siloxanes inherently generate less VOCs. When compared to competitive products, Sika materials produce lower VOC values. Additionally, our superior coverage rates further reduce the impact of the VOCs released.
